Moves disallowed in top-level block

[Buldram]

Description

type MyIsolated[T] = object
  val: T

proc `=copy`*[T](dest: var MyIsolated[T]; src: MyIsolated[T]) {.error.}

block:
  let a = MyIsolated[int](val: 3)
  let b = a

Reports that a must be copied, I'd guess it's being handled as if it's a global variable.
